codeSpark

CodeSpark is a high-tech company that is engaged in creating educational software and games for children.

They are a very small shop, based in Pasadena, California. Tags on their profile include Children, Education and Edutainment. Small teams usually mean fast answers and a product that is still moving, so ask about the roadmap.

Before you book a demo, check the pricing page on codespark.com and ask about contract length. Then, if you end up using codeSpark, come back and tell the next person how it went.
